DEEP-WELL PUMP.

SPECIFICATION forming part of Letters Patent No. 457,244, dated August4,`1891.

Application filed October 8,1890. Serial No. 367,445. (No model.)

To all whom it may concern:

Be it known that I, JOHN BEAN, a citizen of the United States, residingin Los Gatos,

county of Santa Clara, and State of California, have invented certainnew and useful Improvements in Deep-fell Pumps, ot which the followingis a specification.

In deep-well pumps of the class to which the present improvements relatemore particularly the upper portion of the Water-space in the long tubeof the pump, or what I have herein termed the well-tube, constitutes anair-chamber, and the rod of the plunger or bucket extending upwardthrough the head of the chamber 'is connected above it to the lever orhandle for working the bucket. At the point where the rod works throughthe top or head -it has been found difficult to make and preserve atight joint that will prevent the escape of water, and yet will permitthe rod to work smoothly without excessive friction, and the constantleakage at this point is not only a-source of annoyance, but insituations where the pump is exposed to low ternperatu're the pump-rodis often liable to be frozen and become tast. The purpose of the presentinvention is, mainly, to improve the construction in that respect; toprevent the water from collecting in the pump-rod casing and fromescaping around the rod to the outside, and to permit ,the bucket,foot-valve, and all the parts to be raised-and withdrawn from thewell-tube for cleaning and repairs.

The features of the present improvements include apump-rod casing in theair-chamber with a packing at the foot where the rod passes into it, anda waste-outlet or leakageaperture from the casing above the packing tothe outside of the pump-tube, whereby a constant drain-aperture isprovided from the lower part of the rod-casing to the outside of thepump to carry oit whatever water may pass above the packing and find itsway into the casing.

Another feature of the invention consists in an improved joint andpacking in combination with a removable footvalve that is adapted to beraised and drawn out of the well-tube for cleaning or repairing theparts.

In this improvement the foot-valve is oonstructed with a tapering bodyand a iiat projecting rim fitting into an elastic packingring that formsa seat for the rim and a close packing around the tapering body.

The nature of these improvements and the manner in which I haveconstructed and applied the saine will be understood from the followingdescription and the drawings that accompany this specification.

Figure 1 of the drawings is a view of the pump, with a portion of thewell-tube and airchamber broken away. Fig. 2 is a sectional view on anenlarged scale, showing the airchamber, water-distributing chamber,welltube, and foot-valve in longitudinal section. Fig. 3 is a section on'an enlarged scale, showing the foot-valve and coupling at the bottom ofthe Well-tube; Figs. 4, 5, 6, and 7 are views in detail of the parts ofthe waste-outlet or drainage from the pump-rod casing.

A indicates the long tube that extends down into the well and has aninlet at the bottom, controlled by a foot-valve B. This tube is composedot' severalvsections joined by screw-couplings for a deep well or is onesingle tube where the same is practicable. The space in the upperportion of this tube constitutes the air-chamber, and the end -is closedby a hollow head C from the space cx, in which one or more water-tubesDD extend downward in the tube A to carry Water into i the head. Thespace inthe tube A above the mouths of these water-tubes thus forms theair-chamber, while the space in the head is the distributing-chamber,from which the water is carried off through a nozzle, spout, orconducting-pipe C2. The pump-rod E, on the end of which is secured thebucket F, eX- tends upward in theV center ot' the well-tube andair-chamber and through the head O to the outside, where a lever H isconnected to .it t'or working the pump by hand.

or packing is used at that point. The packing at the lower end closesthe casing and is sufficient to insure a tight joint under all ordinaryconditions of work, asits construction is such that the water-pressuretends to hold the packing closely around the pump-rod; but as thepacking wears and becomes set the water iindsits way into the casingandaccumulates in it,or,increasin gin quantityit finds outlet aroun d thepump-rod,whereit ows over the top and down the sides,not onlyto thegreat discomfort of those persons using the pump, but frequently to theserious obstruction of the pu mp,especially in cold climates,where thewater is liable to be frozen around the pump-rod if allowed to collectand stand in the casing. In the present construction a waste passage andoutlet is carried from the lower part of the casing to the outsidethrough the side of the well-tube or air-chamber, to drain the casing ofwhatever water may accidentally pass, and the construction andcombination of the parts by which I have overcome the objections beforementioned form an important feature of this invention.

Upon the lower end portion of the rod-casing, which is screw-threadedfor that purpose, an arm or bridge-piece M is fixed by a threaded ringor socket Mii, which takes over the threaded portion of the casing andis put on before the collar or sleeve N, that holds the packing on thelower end. The piece M, being of suitable length to extend from thecasing laterally outwai'd to the wall of the surrounding tube orchamber, is formed with a passage P, which is in line with both an ap!erture p* inthe side of the casing and an outlet pk* through the side ofthe well tube or chamber. The end of the part M has a circularcup-shaped head M2, with a curved face corresponding in curvature withthe surface ofthe well-tube and with a countersunk recess M3 and athreaded hole for a screwplug R. The head of the plug is somewhatsmaller in diameter than the countersunk recess, and between it and thesides and bottom of the recess is held a cup-shaped washer S, having arim S* that is somewhat broader than the face of the head behind it andeX- tends beyond the edge of the head all around. Between the rim of theWasher and the surface behind it a rubber ring T sets the rim of thewasher outward against the tube-surface and allows the pressure of thewater in the chamber to act against the back of the rim, so thataclosejoint is secured between washer and tube-surface all around theoutlet-aperture.

On the opposite side of the casing, in line with the bridge-piece M, abrace M4 is fixed from the casing to the wall of the well-tube for thepurpose of holding the casing in line and keeping the head of thebridge-piece M tightly against the tube-surface. This brace is a part ofthe threaded socket Ml, and is formed with Aa broad head M5, the face ofplace.

which is curved in a horizontal direction to iit the curvature of thetube, and is tapered in a perpendicular direction to give a faceslightly wedge-shaped. The inner surface of the -well-tube is smooth andflush for the entire length from the drain-aperture to the top, and bytaking out the screws. c3 in the flange of the head C that part israised, bringing with it the water-tubes, the casing, and the pump-rod4and bucket. As the bridge-piece is fixed on the pump-rod casing it isbrought up at the same time, and both the packing at the end and theparts of the drain-outlet can be easily reached for repairs.

The foot-valve has a stirrup with athreaded hole, and the end of the rodis screw-threaded,

so that by running the rod `down to the bottom of the well-tube andturning it around lthe foot-valve will be attached to the rod andcan bedrawn up with the other parts. Similar provision is made in other pumpsof this class, however, andIclaim no novelty for that feature of itselfin mypresent invention; but the form of the rod and the socket or guidethrough which it works is different from those hereto/fore used, andbesides being quite simple in construction it serves to hold the rodwithout vexcessive friction, and at the same time when the foot-valve orparts inside the well-tubes are to be removed it allows the rod to bereadily screwed into the foot-valve stirrup and then drawn up and out ofthe tube without taking off the guide. This construe` tion of the rodand guide will be understood from Figs. l and 7. The guide-plate U issupported above the top of the pump on three standards U*, andhasacentral circular opening U2 about equal to the size of thecylindrical part of the pump-rod below it; but the top portion of therod that works in the guide is flattened on opposite sides with theedges rounded to correspond to the curved edges of the opening. Thelever H is pivoted at h to the flat part of the rod, and is detachedwhen4 the rod is to be turned around in the guide to fasten the end intothe foot-valve. The supports U* are ixed on the top of the head C byscrews U3. The foot-valve B isv formed with a tubular body Bi, somewhattapering on the outside, and a iat flange B2, projecting all aroundabout equal in outside diameter to the bore of the tube, so that whenseated on the bottom packing Y the ange covers it and fills the spacebetween the walls of the tube. The bottom of the tube has a iianged headZ fitting a corresponding fiange in the bottomreducing coupling Zt, andthe packing Y is clamped between the two anges, which are drawn togetherby bolts and nuts. A recess Z3 is formed in the bottom coupling to letin the packing, and the end of the tube is seated directly on thepacking. This secures a tight joint and also serves to hold the packingin The packing is made of elastic material, preferably of rubber. valveis pressed down into place, its ange IOO IIO

sets closely down against the packing, while the tapering body passingthrough the center aperture causes the packing to bind around thetapering surface, thus insuring a tight joint at the bottom of the tube.

It should be mentioned with respect to the general construction of thewater-distributin g chamber and pump-rod easing that the same partsconstitute features of former inventions that have been made by me thesubject of a prior application for Letters Patent filed in the UnitedStates Patent Oee November 4, 1889, Serial No. 329,224, and no specialclaim is made, therefore, to such parts of themselves in the presentinvention.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a deep-well pump, the combination of a well-tube, a head or tophaving a water-distributing chamber with a depending water tube or tubesextending downward into the Well-tube a pump-rod casing having awatertight packing at the lower end and fixed at the top end into thebottom of the water-distrbuting chamber, the laterally-extendingbridge-piece or arm, in which is a water-passage, an outlet-aperture inthe surrounding well-tube and an aperture in the rod-casing connectedtogether by the said water-passage and forming a drain-outlet from therod-casing above the rod-packing to the outside of thewell-tube,`substantially as described.

2. In a deep-well pump, a pump-rod casing extending into theair-chamber, a Well-tube having a water-tight packing on the lower end,and the bridge-piece having a laterallyextending passagew'hich is inline with an outlet in the side of the casing and connects the same withan outlet-aperture in the side of the well-tube, the packing-diskextending beyond the head of the bridge-piece, and the brace on theopposite side of the casing, all in combination, as described.

3. In combination with the bridge piece fixed on the rod-casing andhaving a longitudinal passage which is adapted to connect the space inthe rod-casing with an outletaperture in the surrounding well-tube, ofthe packing-disk, clamp-screw, and elastic ring ybetween the disk andthe head of.the bridgepiece, as and for the purpose set forth.

4. The oombination,with the rod-casing having a water-tight packing atthe lower end and a drain-aperture in the casing above the packing, ofthe bridge-piece having a screwthreaded plug with a longitudinal passagein line with the casing-aperture, ak countersunk head on the outer endof the bridgepiece corresponding in curvature with the curved wall ofthe surrounding well-tube, a circular packing disk or Washer having aprojecting rixn, the elastic ring behind the washer und er the rim, andthe brace on the opposite side of the casing in line with thebridgepiece, substantially as described.

5. In a pump having a stock formed of a tube, the combination of laremovable top or cap, a pump-rod casing having its upper end fixed tothe cap and extending downward, and a bridge-piece secured on the lowerend of the rod-casing having a passage through it connecting an aperturein the casing directly with the outside of the pump through an aperturein the pump-stock, the said cap, pumprod casing, and bridge-piece beingremovable, as described.
